Overview
- OpenAI announced on Friday that the GPT-5.6 family is generally available, moving the model out of its late-June limited preview into broad public release.
- GPT-5.6 comes in three variants — Sol as the flagship with an Ultra mode that coordinates multiple agents, Terra as a balanced option, and Luna as the low-cost, fast option — with explicit per‑million‑token input and output prices.
- Access is tiered: Sol is available to Plus, Pro, Business and Enterprise subscribers while Terra is offered to Free and Go users, and OpenAI published staged rollout schedules for desktop, web and mobile access.
- OpenAI introduced ChatGPT Work, an agent that can connect to apps and files, break projects into multi-step tasks, run workflows over hours and deliver finished documents and presentations, with initial access prioritized for Pro, Enterprise and Edu users.
- The company rolled out a renamed desktop app that unites Chat, Work and Codex, set a Sept. 1 deadline requiring hardware passkeys for Advanced Account Security to keep high-risk cyber capabilities, and published internal benchmarks claiming gains over Anthropic with limited third‑party verification.
